我队七七年以前钻杆折断非常严重。以钻杆折断为主的孔内事故时间，七七年高达17.6％，采取措施后，七八年为7％，七九年第一季度为1.7％，累计到四月十五日为2％。下面介绍我队锻工组是怎样提高加工钻杆质量的。一、树立“质量第一”的思想以往，我队负责墩钻杆的锻工组在墩钻杆方面，质量要求与检查不严，加之墩杆工作属于重体力劳动，个别人，怕出力图省事，过去墩杆加工一般是“一火”、“二火”，每火墩一、二次，不管达没达到 The drill pipe was broken severely before our team made seven or seven years ago. The accidents in the boreholes, where the drilling rods were broken, were as high as 17.6% in 1977. After taking measures, they were 7% in 1978, 1.7% in the first quarter of 1979, and 2% as of April 15. . Here’s how our team of forgings improves the quality of the drill pipe. First, establish the “quality first” thinking In the past, our team is responsible for the pier drilling rod in the drill pipe, the quality requirements and lax inspection, coupled with the pole work is heavy physical labor, individual, afraid of effort Conveniently, in the past, pier processing was generally “one fire” and “two fires.” Each fire pier was one or two times, regardless of whether it was reached.
